| 摘 要： | Xanthenedione derivatives have held considerable interests in recent years, since theyconstitute a structural unit in a number of natural products1 and have been used asversatile synthons because of the inherent reactivity of the inbuilt pyran ring2. Usually,poly-hydrogenated xanthenediones (3, Scheme 1) can be obtained through the acid orbase catalyzed condensation of appropriate active methylene carbonyl compounds withaldehydes. But this method is not very satisfactory because of the prolong… |
